Questions : Engine, Combat system, Object Interaction

[zoroztheg4mer]

Is the new engine similar to the penumbra engine, or is it completley re-built ?
Will there be alot of interaction with objects as in Penmubra, or will you just simply pick up an object, or open a door with the click of a button ?
What would work best in your opinion ?
The interaction with the objects in the Penumbra series really added to the game giving it a much more realistic feeling. I think that the interaction with objects is a great way of making the game more realistic making it easy to solve a puzzle in many different ways. This would definietly work for your advantage imo on Amnesia.

Will weapons be available to use ?
If so, will the combat-system be easier to controll than in Penumbra, or will it have the same kind of system ?
